I have noticed that I have trouble displaying image thumbnails when I have SPI enabled on my Wireless 11n cable/dsl firewall router.
For example, when performing image searches in google image search, many times the thumbnails of images returned in the search will not be displayed. A place-holder is displayed instead.
When I disable SPI, the image thumbnails are all displayed in the results.
The symptoms are the same with two computers attached to my router.
There are many settings associated with SPI. I have no idea which one(s) might be causing the problem. Which SPI setting should I change?
Does anyone have any trouble-shooting suggestions?
Thanks.
